  •  Restart Cisco Tomcat Service by Logging into Publishers/Subscribers CLI on which Certificates were regenerated by running the command “utils service restart Cisco Tomcat”
  • Try to access Service Pages Nodes from Publisher and the subscriber nodes should be accessible. If not, try rebooting the cluster.
